VAPOR INCANDESCENT-LAMP BURNER.

l SPECIFICATIONfor-mng part of Letters Patent No. 725,740, dated April21, 1903.

Application filed April 30, 1902.

.at the burner-tip and subsequently mixed with air and burned toproduceA a flame of high temperature suitable for use with incandescentmantles.

My invention has reference more particularly to burners of the classknown as central-draft burners, although some of its features areapplicable also to other kinds of burners, as will be apparent from thefollowing description.

The object of my invention is to produce a vapor incandescent-lampburnerrwhich shall |be reliable in operation, capable of easyregulation, and which may be readily lighted without the risk ofdamaging the mantle.

A further object of mylinvention is to provide a ready means forextinguishing the lamp and also for giving to the vapor-gener- -atingportion thereof a self-regulating character which will regulate thevapor-producing action and prevent an oversupply of vapor from thewick-tube or tip at which the vapor is generated `by the heating actionof :the gasifier. Y

My invention consists also in other details olf-constructionandcombination of parts, as hereinafter more particularly described andclaimed.

In the accompanying drawings, Figure l is a side elevation of alamp-burner embodying my invention, and Fig. 2 is a vertical centralsection through the same. Fig. 3 is a view of the gasiier and mixerlooking from beneath. Fig. 4 shows a portion of the air-distributerwhich encircles the lower edge of the mixer and vaporizer.

l indicates the base of the burner, constructed in the. usual way topermit it to be detachably secured to the mouth or opening of anoil-font, while 2 indicates the sheetmetal shell or casing, providedwith openings for the inlet of air to the burner and rising Serial No.105,300. (No model.)

from said base, as shown. At the top thereof` is provided anair-distributer 3, located within the detachable chimney-supporting ring4, which preferably has a cylindrical inner portion 5 risingconsiderably above the burner, so as to encircle andfprotect the mantle6, while aiding also to direct the air admitted around the base of lthelamp-chimney through the openings 7 and cause it to pass along theoutside of the lowerA Vportion of the mantle and to the air-distributer3. -The distributer 3 serves, as usual, to provide a uniform or equablesupply of air to the burner. Instead of making the same of perforatedsheet metall prefer to construct it in the manner shown byforminganumber of fine slitsextendingdownwardly from the edge of said`distributer, as clearly shown, and to secure astillbetter distribution Igive said slits an inclination from the perpendicular, as shown.r InFigs. 1 and 2 the size of the slits is shown exaggerated and theirnumber as smaller than would be preferable in practice. They should beas many in number as practicable and each of very narrow width, so as toproduce, in effect, a brush-like structure the bristles of which standupright and form a narrow line of bristles separated by very finespaces. A nearer approach to the actual number and width of the slits isshown in Fig. 4. The sheet-metal ring of which said air-distribu ter isformed may constitute a continuation ot' the shell 2 or may be supportedand suitably secured to an inwardly-extending shoulder at the upper endof said tube. A section of said distributer, or,wif desired, the Wholeof the same, is made capable of being lifted away from immediateproximity to the tip of the wick-tube for a purpose to be presentlydescribed.

. 8 is the gasier or mixer, supported centrally on the burner and actingat its lower edge as a vaporizer to vaporize the oil drawn by capillaryaction up to the wick in the end of the wick-tube. Said vaporizerbecomes highly heated by the burning gas, and the heat beingcommunicated to the lower edge thereof, which is in immediate proximityto the end of the wick-surface, produces the petroleum-vapor, which,being mixed with air, is burned after the manner of a gas-flame. Theperforations in the mixer or gasiier 8 lOO serve to convey air broughtup centrally through the wick-tube to the vapor circulating from the endof the wick around the lower edge of the gasier or vaporizer.

The gasier 8 may be made of lava composition, preferably, and the plateat the lower edge thereof may be made of metal secured thereto in anysuitable manner. The plate forming the lower edge is made irregular orcorrugated, as shown in the View Fig. 3, to form a number of passages oropenings through which the vapors may pass, while at the same time theportions between said openings or grooves will come down close to thewick and will serve the purpose of generating the vapors by their heatand will at the same time prevent the dame from forming at the wickitself.

In order to prevent the overproduction of vapor by the gasilier after itbecomes heated and to secure a self-regulating action, I propose to somount or construct it that by the differential heating effects of thefiame upon the metal parts it will be automatically lifted away from thewick with increase of the heat. For this purpose I mount the gasier upona stem or rod 10 of some material which has a large coefficient ofexpansion by heat and which may be fastened by a' screw-joint orotherwise to the stem 11, suitably supported on cross-bars 12 within thewick-tube 13. Cobalt may be used for t-his purpose.

After the preliminary adjustment of the gasiiier or vaporizer to startthe lamp with the proper kind of a dame it will be automatically liftedby the effects of the heat, so that its lower edge will move away fromthe wick, and thus prevent the same from furnishing an oversnpply ofvapor. The operation is practically a regulation of the vapor-producingaction of the vaporizer or gasifier.

Passing centrally down through the burner is a rod 14, upon which themantle may be supported. This rod 14 extends through rods 10 and 11 andmaltv be securely fastened at the lower end of the wick-tube by means ofa setscrew, as shown, or by other devices.

The rod 11, which supports the gasifier, iS mounted in the cross-arms12, so as to be capable of vertical motion therein, and is adapted to beadjusted up and down by means of the adjustinghandie 15, secured to astem which rotates in bearingsin the tube and carries apinion engagingwith a rack 16 upon the rod 11, as shown more clearly in Fig. 2. By thismeans the gasifier and means for adjusting the same are a part oftheburner construction and may be applied and fitted to any type of font orlam p-base.

The Wick-tube 13 is secured to or may be a part of the base 1in theusual or proper manner and is furnished with openings, one or more, asindicated at 17, to allow air to pass up through the center of the sameto the inside of the burner-tip. The wick (indicated at 18) may as toits lower portion be of cotton or other material, as usual in the art,having good capillary action and capable of adjustment up and down inthe Wick-tube by means of the spring ring or clip 19, encircling thewick and secured to the rod 20, which is capable of operation by meansof the lever 2l or other device mounted on the shell 2, the wholeforming a wick-lift for the capillary feed portion of said wick. The tipor upper end of the wick exposed at the end of the wick-tube and whichis subjected to high heat is made of a section or piece 22 of someporous, but non-combustible material set in the end of the tube anddisconnected from the capillary feed portion 18, as clearly shown in thedrawings. The clip portion 22 may be made of fire-clay. The portion 18when adjusted up into contact therewith by the lever 21 will feed oilthereto while the lamp is burning. By .throwing the l'ever so as tolower the capillary portion 18 just out of contact withthe tip portion22 the supplyof oil to the wick end 22 is shut off and the lamp becomesextinguished. On the lower end of the wick-tube is a ring or frame 23,carrying a number of spring-fingers 24, adapted to hold su pplementalwicks 25 in contact with the wick 18 and to aid thereby in drawing upthe oil from the oil-font. The supplemental wicks 25 pass up throughopenings in the frame 23, as shown at the left of Fig. 2.

The lighting attachment whereby the lamp may be lighted withoutdisturbing the chimney or the mantle 6 is provided by mounting asupplemental vertically-adj ustable lighter 27 on the outside of thewick-tube or on any othersuitable support. This lighter consists of awick-tube guided in a projection or tube 28 and furnished with anoperating-knob 29. Within the tube 27 is a wick which leads from theoil-font and at its tip or burner portion is furnished with a piece 30of rock-asbestos or other suitable material. I prefer to userock-asbestos because ofA its non-combustible character, although lImight use other non-combustible material for this purpose.Rock-asbestos, moreover, has the advantage that its capillary capacityis comparatively limited, so that after being lighted at its tip it willburn for a very short time and will then, through the exhaustion oftheoil in its pores or capillaries, become automatically extinguished.After a time, however, it will absorb sufcient oil from the wick in tube27 and will be capable of being lighted again. By this means I securethe following advantagesz' First, I avoid unnecessary consumption ofoil; secondly, the tendency to iiickering in mantle-lamps which wouldresult from the presence of a flame at the lighting-burner is avoided. Iprefer to use asbestos rock for the tip because it has the peculiarquality just described of absorbing just sufficient oil to produce aflame for a very short time, sufficient, however, to light the lamp,while at the same time it is free from the objections attaching to theuse of plaster-of-paris, porcelain, or other refractory porous substanceIOO which have a decided tendency to finally become clogged and losetheir capacity for absorbing oil. The lighter 30 is accessible throughthe door 31 in the side of the tube 2.

` A spring 33, applied, as shown, between a pin on the tube and the topplate or portion of the base l, serves automatically to retract thelighter when it has-performed its function of lighting the burner 22.

In order to prevent the lighter 30 from being extinguished when raisedinto the space between the air-mixer 3 and the end of the vapor-burner,I mount a section of air-distributer 3 immediately overthe lighter 30,so that it is capable of being lifted out ot the way and allowing a freesupply or" air to the lighter-tip 30. For this purpose a section oi'said air-distributer may be secured to asprin g 35, which is secured tothe wick-'tube and is arranged in position to be engaged by a projection 36, extending laterally from the lightertip 2,7, when the same israised by the knob 29 for the purposeof lighting the main burner. Tolight the lamp, -the tip 30 is ignited by a a match and is raised topositionwhere the flame of the tip 30 will ignite the oil in the endsection 22 of the main wick, oil having been supplied to the latter byproperly manipulatingthe Wick-lift 21 when itis desired to start thelamp. After the burner 22 has been lighted the gasi-iier 8, which hasbeen lifted by the knob 15, becomes heated and bysaid knob is thenadjusted down until the flame is extingushed upon the tip 22, whichthereafter acts to supply the vapor by reason of the heat of the ring 9.gasifierS is adjusted until the proper quality of iame is produced inthe space above said gasiiier. To extinguish the lamp, all that isnecessary is to operate the wick-lift 2l to cut off the supply of oil'to the tip 22.

In place of rock-asbestos for the tip 30 I may use any desired material.The tip,how ever, should have a limited capillary capacity, so that itwill Aimmediately burn itself out, and thus automatically extinguishitself and nally becoming charged again with oil in the course of timeready for another use.

W'hat I claim as my invention is- 1. In a vapor incandescent-lampburner, the combination with the burner having a capillary oil-supply,of a vaporizer above the same and an eXpansible support for saidvaporizer exposed to the heat of the burner so as to automaticallyadjust the position of the By the knob 15 thesisting ofasheet-metal'ring whose upper edge is divided to form a brush-likestructure between the bristles of which the air-supply passes. Y Y

5. In alam p-burner, an air-distributer consisting of a sheet-metal ringwhose upper edge is divided into a number of bristle-like strips adaptedto form a brush-like structure the bristles of which are inclined, whilethe spaces between the bristles form passages for the air-supply.

6. In a lamp-burner, an oil-lighter having a lighting-tip composedof amaterial that has a limited capillary capacity, whereby the lighter Willautomatically extinguish itself immediately after being lighted butlwill again recharge itself for another operation.

7. In a lamp-burner, the combination with a wick-tube, of a supplementalwick-tube vertically adjustable in suitable guides upon the side of thevmain wick-tube, and means for adjusting the same up and down to bringthe tip of the supplemental wick-tube into and out of proximity to themain burner.

8. In a lamp-burner, the combination substantially as described with avertically-adj ustable lighter, of an air-distributer whose partsimmediately over said lighter are also capable of vertical adjustment,and means for lifting the same out of normal position by ICO the actionof the lighter when said lighter is raised to light the lamp.

9.' In a vapor lamp-burner, a gasiiier or vaporizer made irregular onits portion in immediate proximity to the lamp-wick, as and for thepurpose described.

10. In a lamp-burner, a gasifier or vapo- York and State of New York,this 28th day of April, A. D. 1902.
